quantity of certain materials. However, regardless of size of granules,the diillculty of dislodging and discharging these materials fromhoppers and` hopper cars is present with all such materials althoughpossibly to different extents with the different sizes of granules ordifferent kinds o! materials;

Numerous efforts have been made by prior workers in the art to provideapparatus which would jar. jolt, agitate or otherwise, cause granularmaterial-containing containers, such as hopper cars, to vibrate and thusloosen the granular material and cause it to iiow out through an openingprovided therefor in the container or car. So far as I am aware,however, none of such devices has been entirely satisfactory.

The present invention solves this long-standing problem in an eminentlysatisfactory manner for it provides the desired vibration of the solidscontainer with substantial freedom from breakage of parts.

The herein illustrated embodiment of the present invention comprises tworectangular frames with springs interposed therebetween so that oneframe may rest on the upper edges of a hopper car and the second framemay be resiliently supported by the irst frame on the interveningsprings, a motor near one corner of the second frame to rotate anunbalanced body supported by the first frame, and a weight located moreor less vdiagonally opposite to the motor and serving as a partialcounterbalance therefor. It will be understood, however, that othermodifications of the present invention are comprehended herein and areintended to be included within the scope of what is claimed in thehereinafter appended claims. I

In the drawings which accompany and form a part of this specification,

Fig. 1 is a top plan view, with parts broken away and other parts insection, of an embodiment of the present invention suitable for use on arailway hopper car;

Fig. 2 is an end elevational view of the device 3 Claims. (Cl. 214-44) 2Fig. 3 is' a view taken on lines 3-3 of Fig. 1V showing the motorcounterweight.

In the drawings, I indicates the upper portions of the sides of arailroad hopper car. The shaking` device embodying the present inventionis shown in Fig. 2 as resting on the top edges of sides l.

The shaking device illustrated comprises a lower rectangular frameconsisting of sides 2 to rest on the upper edges of sides I of the carand arched plates 3 connecting the sides 2, and a cover 4 is secured tothe top edges of plates 3. Near its midportion cover 4 is provided with`lifting lugs 5 by which the device may be suspended from a cable forlifting, lowering andtransporting. Adjacent the corners of the lowerframe are disposed a plurality of springs 1 which rest on the ilrst orlower frame and support an upper or second frame.

The upper frame is rectangular and consists of side members 8 and crossmembers 9. A motor I5 is mounted on the upper frame near one cornerthereof, and is adjustable toward and away from the longitudinalcenterline of the device, L e., the longitudinal axis of the hopper car.

A plurality of springs I6 similar to springs 1 are positioned betweentheA frames beneath the m o t o r. Approximately diagonally oppositemotor I5, a Weight consisting of plates I8 and approximately equal toone-third of the weight of the motor is attached to the upper frame.This weight partially counterbalances the motor when the device is inoperation. i

The cross plates 3 of the lower frame are provided with bearing housings20 which support bearing races 2l in which a shaft 22 is mounted forrotation. A pulley 23, at one end of shaft 22 is aligned with pulley 24on the rotor shaft of motor I5, and drive belt 25 transmits rotarymotion of pulley 24 to pulley 23.- Shaft 22 is provided-between plates 3with one or more weights 26 which rotate therewith and which are un,-balanced. The unbalancing of these weights may be achieved either bymounting them eccentrically on the shaft 22 or by `mounting themconcentrically and then adding weight to one side thereof.

The operation of the above described apparatus is substantially asfollows: The device, supported from lifting lugs 5, is lowered onto thetop of a hopper car to rest on the sides I thereof substantially as isshown in Fig. 2. The discharge doors (not shown) in the bottom of thecar are opened and the motor vI 5 is energized. The motor drives belt 25thereby 4rotating shaft 22 and weights 26 thereon. It is believed thatthe rotation of i weights 26 tends to move the lower l frame in acircular orbit but that gravity interferes with the tendency of theframe to move upwardly in that orbit and the car interferes with thetendency of the frame to move downwardly in that orbit. Thus. theresulting movement of the frame. is in an oval orbit-having its majoraxis in a horizontal plane. The movement of the lower frame induced bythe rotating unbalanced weights is transmitted to a certain extent tothe upper frame through the springs and, due to the lag in transmission,the movement of the upper frame is not exactly in synchronism with thato! the lower frame. However, the two frames are near enough insynchronism to keep the drive belt 25 in driving tightness.

It is believed that the counterweight i8 modl- 'iles and tends toequalize the forces applied to the several springs when the device lsoperating for with the counterweight present the life of thel springs ismany times that attained when the counterweight is absent.

` As a result of thek present invention and the present combination ofsecond frame, a motor near one corner of the second frame, acounterweight for the motor on the second frame near the cornerdiagonally .opposite to the motor, and a rotatable, unbalanced body onthe first frame and connected to the motor for rotation thereby.

2. A shaker comprising a rectangular frame having side members to reston the top edges o! a hopper, a second rectangular frame above said rstframe, springs supported by the rst frame near the corners thereof andsupporting the second i'rame, a motor near one corner 0i the secondframe, springs extending from the ilrst frame to the second framebeneath said motor and partially supporting the motor, a counterweighton the second frame near the corner thereof diagonally opposite to themotor and approximating one-third of the motor weight, and a rotatable,unbalanced body on the ilrst frame and connected to the motor forrotation thereby.

3. A car shaker comprising a rectangular frame having side members torest on the top edges o! the sides of a hopper car, cross membersconnecting said side members, an unbalanced member rotatably supportedby said cross members, a second rectangular frame above said ilrstframe, springs between said frames supporting said second frame fromsaid rst frame, a motor near one corner of the second frame, acounterweight on the second frame near the corner thereof diagonallyopposite to the motor, motor supporting springs between the framesbeneath the motor and means connecting the motor and rotatable memberfor rotating the latter.
